[0017] Example 1
[0018] In order to achieve the above technical effects, the production method of suede elastic fabric in Example 1 includes the following steps:
[0019] S1: Configure the raw material fiber of the fabric. The warp and half of the weft of the suede stretch fabric are made of yarn made by blending wool and vinylon, and the other half of the weft is made of core-spun yarn made of elastic fiber core yarn sorona staple fiber; The content of vinylon in the yarn made by blending wool and vinylon spinning is 5%;
[0020] S2: The above-mentioned fibers are respectively dyed and combed to make wool tops, and the grey fabrics are obtained by drawing, roving, spinning and weaving;
[0021] S3: The grey fabric obtained from S2 is subjected to de-dimensionalization, drying, brushing, shearing, shaping, steaming, pre-shrinking and finishing. The pre-shrinking process parameters are: vehicle speed 5m / min, steam consumption 50%, overfeeding 10 %.
[0022] The shearing process param...
Example Embodiment
[0027] Example 2
[0028] The difference between Embodiment 2 and Embodiment 1 is:
[0029] S1: The content of vinylon in the yarn made by blending wool and vinylon spinning is 15%;
[0030] S3: The pre-shrinking process parameters are: vehicle speed 10m / min, steam consumption 75%, and overfeeding 10-15%.
[0031] The shearing process parameters are: 20m / min, the spacing is 1mm, and the shearing method is two positives and one reverse.
[0032] The decantation process parameters are: decantation temperature is 115℃, time is 70s, pressure roller pressure is 3.5bar, and cloth tension is 90kg.
[0033] The shaping treatment is a narrowing machine, the narrowing range is 3%, the temperature is 170°C, and the vehicle speed is 18-22m / min.
[0034] The weight ratio of elastic fiber core yarn and sorona staple fiber surface yarn in the core yarn is 1:1.
[0035] The de-dimensional treatment temperature is 95°C.
Example Embodiment
[0036] Example 3
[0037] The difference between Embodiment 3 and Embodiment 1 is:
[0038] S1: The content of vinylon in the yarn made by blending wool and vinylon spinning is 10%;
[0039] S3: The pre-shrinking process parameters are: vehicle speed 7m / min, steam consumption 67%, overfeeding 12%.
[0040] The shearing process parameters are: 19m / min, the gauge is 0.85mm, and the shearing method is two positives and one reverse.
[0041] The process parameters of decantation are: decantation temperature is 110℃, time is 60s, pressure roller pressure is 3bar, and cloth tension is 75kg.
[0042] The shaping treatment is a narrowing machine, the narrowing range is 2.2%, the temperature is 165℃, and the vehicle speed is 20m / min.
[0043] The weight ratio of elastic fiber core yarn and sorona staple fiber surface yarn in the core yarn is 4:5.
[0044] The de-dimensional treatment temperature is 90°C.
